Specification forming part of Letters Patent No. 19] ,B0@, dated May 22, 1877; application filed March 24, 1877.

To all whom it may concern:

Be it known that 1, JAMES H. CAMPFIELD, M. D., of Ottawa, in the county of La Salle and State of Illinois, have invented a new and useful Improvement; in Cigars; and I do he'r'eby declare that the following is a full, clear, and exact description of thesame The object of the invention is to render the smoke of cigars'made of tobacco less offensive and injurious;. and to this end, in the process of manufacture, I form a chamber or cavity in each cigar, and insert therein a piece of sponge or other suitable absorbent material, which has been saturated with a solution of tannic acid, for the purpose of extracting from the smcke drawn through the cigar the nicotine and empyreumatic oil, which are poisonous and inimical to health.

in the accompanying drawing, forming part of this specification. Figure 1 is a side view of a cigar, with part broken away to show the location of the cavity; and Fig. 2 is a similar view, showing the sponge inserted in the cavity. I v

The cigar A may have the usual or any preferred shape. The cavity a for receiving the a cone, with its base toward the square butted' or lighting end of the cigar, so that the sponge which fills the cavity may the better intercept the smoke, and thereby cause a more thorough absorption at nicotine.

vThe rationale of my invention is as'follows: The nicotine, which is the active and poisonous principle, is an alkaloid, and hence a salifiable base, which will combine with the tann'icacid with which the sponge has been satu- ,rated. Therefore, as the smoke permeates or passes in contact with the sponge, the nicotine is instantly taken up. The empyreumatic oil is also absorbed, to a greater or less extent. so that the smoke is rendered comparatively innocuous.

What I claim is- A cigar provided near its mouth end with a porous substance saturated with tannic acid, as and for the purpose specified.
